From 4ab2a7878fa56ae7581bf8a94049b355c730aef0 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Sun, 15 Jan 2017 18:50:57 -0500 Subject: [PATCH] scsi: ncr5380: Resolve various static checker warnings Avoid various warnings from "make C=1" by annotating a couple of unlock-then-lock sequences, replacing a zero with NULL and correcting some type casts. Also avoid a warning from "make W=1" by adding braces. Signed-off-by: Finn Thain Tested-by: Ondrej Zary Tested-by: Michael Schmitz Signed-off-by: Martin K.
